SPECIFICATION forming part of Late. Patent No. 637,764, dated. IN'ovember as, 1899.

Application filed June 3,1898. Serial No. 682,422. (No model.)

T0 all whom it may concern:

Be it known that I, JOHN W. CAMPBELL, of New York, (Sea Oli ff,) in thecounty of Queens and State of New York, have invented an ImprovedCylindrical Neostyle, of which the following is a specification.

Referring to the accompanying drawings, Figure 1 is a rear elevation ofmy improved neostyle. Fig. 2 is a side view of a form of severingmechanism contained in the machine, a portion of this figure being takenon line or x of Fig. 1. Fig. 3 is a front end view of the machine shownin Fig. 1. Fig. 4 is a top plan view of the machine. Fig. 5 isa frontside elevation. Fig. 6 is a transverse sectional detail at line y y ofFig. 5 of the swinging frame which supports the platen-roll of theneostyle. Fig. '7 is a rear side elevation of a portion of the machine,the severing mechanism being removed for greater clearness. Fig. 8 is alengthwise central section of the machine with the severing mechanismremoved, on line 2 z of Fig. 4.

The cylindrical neostyle (and comparable machines) prints from astencil-like impression-roll on tissue or other thin paper, and wherelarge numbers of copies are wanted for immediate use much difficulty hasbeen encountered in dryingthe copies rapidly enough for desirably-promptdistribution.

One object of my invention is to blot or otherwise get rid of the freshink on the copies as fast as they come from the printing-rolls, and asecond object of my invention is to sever the copies from a continuousweb as fast as the printed copies are made apparently dry in themachine.

My invention consists of the combinations hereinafter claimed.

In the drawings illustrating the principle of my invention and the bestmode now known to me of applying that principle, 1 represents the usualstencil-sheet of the cylindrical neostyle, and 2 the gear at the end ofits impression-cylinder, whereof the stencil 1 is a part. Theink-roll 3is mounted as usual and in a manner and in connection with devices tooconstruction of the neostyle proper, and 4, 5,

and 6, respectively, represent the driving-gear of theimpression-cylinder,the pinion meshing therewith and rotated by thecrank, and the crank. It will be convenient to refer to the handle sideof the machine as its front side. The shaft7of the usual platen-cylinderis provided with the bevel-gear 9. Shaft 7, as usual, carries a gear 10,which meshes with an end gear2 of the impression-cylinder. The stencil 1extends only part way around the impression-cylinder-from cross-bar 11to cross-bar 12. Bed 13 extends, as usual, on both sides of theplaten-roll on shaft 7 and in my improvement is extended between theblotting-roll 14 and its cooperating feedroll 15, which is mounted ontransverse shaft 16 at a suitable distance from the shaft 7and carries abevel-gear 18, which meshes with a bevel-gear 17 on shaft 19, whichextends lengthwise of the machine and carries a bevelgear 20, with whichthe bevel-gear 9 (on shaft 7) meshes. As web 21 is printed and fed frombetween the impression-rolland platenroll its free end is led (by theoperator) between the blotter-roll 14 and cooperating feed-roll 15, thetwo sets of rolls-the impression-roll and platen-roll and theblotter-roll 14 and feed-roll 15-being geared to rotate at the samespeed. These two sets of rolls are driven by power applied to one of theprinting-rolls, as by handle 6 on the impression-cylinder, and throughthe interworking gears 9 and 20, shaft 19, and interworking gears 17 and18. Roll 14 is faced with blotting-paper or other absorbent material,and the printed portions of web 21 (of tissue or other suitablematerial) are blotted as fast as printed and so made ready for mailingor other use. When the blotting-paper does not serve to absorb the freshink rapidly enough,

I heat one or both rolls 1 4 and 15 by introducing any suitable heater,such as a gasfiame 22 within hollowshaft 22 of blotterroll 14 or withinthe shaft 16, which may be made hollow for this purpose. Ordinarily theblotter-cylinder will do the work of absorption without the heater,which may be of any suitable kind-gas, oil, or electric, as desired. Itis customary to have the platenroll movable toward and away from theimpression-roll, as is well known to all skilled 'in the art, and Iconsequently mount the journals 23 of shaft 19 011 one of the swingingside bars 24, through which the shaft 16 loosely passes. (See Fig. 6,)Shaft 16 isjournaled in the vertically-adjustable boxes 25, mounted inguideways 26 in the side frames- 27,'which are here shown as connectedto the usual side frames 28 of the neostyle. These journal-boxes aresupported on screws 29,

which serve to press the blotter feed-cylinder 15 toward its cooperatingblotterroll 14. Shaft 7 is journaled inand near thefree ends of theswinging side bars 24 24, the free ends of these bars being pulledtoward the impres I adjusted to be pushed away from the impression 7roll (or stencil carrying cylinder) by means of the cams 31, which aremounted in side frames 28 and work on the ends 32 of the swinging sidebars. platen-roll 7 and blotter feed-roll 15 is'desirable in cases ofvariation in thickness of stock and for obtaining desiredpressuresbetween the platen-roll and stencil and between the blotter-roll and itscooperating feed-roll 15. The rolls 7 and 15 may be covered or facedwith anysuitable material, and the absorbent sheet 14 is intended to berenewed as fast as blurred by the absorption of ink. I

I As the printed and blotted web issues from between the blottingmechanism, consisting, essentially, of two members preferably, but

not necessarily, in the form of rolls 14 and 15,-

. the web may be severed by shears in the hands of the operator; but, ifdesired and as I prefer, an automatic severing mechanism may beemployed. In thedrawings I show one of many mechanically-possibleformsof severing mechanism. (See Figs. 1, 2,

3, and 4.) On the shaft 33 of the blottercylinder (the shaft beingjonrnaled in side frames 27) I mount a cam 34, the high point 35 ofwhich engages rod 36 to actuate the mov-,

able member of the severing mechanism at the instant the printed andblotted section of the web issues from rolls 14 and 15. Rod '36 ismounted vertically in bearings 37 on side frame 27 and is held up. by aspring 38 between the lower bearing 37 and acollar 39 on the rod. Thelower end of the rod is loosely connected with the lever 40, pivoted at41 to the. frame of the neostyle; The forward end of the lever engagesthe movable severing member 42 and moves it toward and away from thestationary member 43, which extends transversely across the machine withits upper edge in theplane of the bed 13. As the high'point of the cammoves out of engage ment with the rod the spring 38 pushes the rodupwardly, so that the latter pulls up the 'rear end of the lever 40,throwing down the front end of the lever and moving cutting member 42away from stationary cutting member 43. I 7

The adjustability of the The machine above described may be alteredinmany of its mechanical features without departure from my invention.

My improved neostyle is especially useful in oflices from which it isdesired to send, at certain business hours, large numbers of reportsspeedilyafter the information therein is obtained and with such celeritythat there is not time for, the printed sheets to be dried in theordinary way. r 7
